Preheat the oven to 375℉.
Cook the lasagna noodles according to package instructions until al dente. Drain and rinse with cold water to avoid sticking. Set aside.
Mix the ricotta, spinach, chicken, parmesan, egg, garlic powder, onion powder, Italian seasoning, salt, and pepper in a large bowl.
Ladle 1 cup of the Alfredo sauce into a 9x13" casserole dish and spread it around evenly.
Lay a lasagna noodle flat on your work surface. Make sure it no longer has any excess water. Spread about 3 tbsp of the ricotta mixture over the noodle, then drizzle 1-2 tbsp Alfredo sauce over the ricotta mixture. Roll the noodle tight, but without squishing the filling out the sides of the roll. Place the roll in the casserole dish. Repeat with the rest of the noodles and filling.
Top the rolls with remaining Alfredo sauce and mozzarella cheese.
Cover the casserole dish with foil and bake for 20 minutes. Remove the foil and bake for another 10 minutes, or until bubbly with brown spots beginning to form on the top.
